Commit Message

Peter Ujfalusi Feb. 10, 2022, 10:55 a.m. UTC
Add a new client driver for probes support and move
all the probes-related code from the core to the
client driver.

The probes client driver registers a component driver
with one CPU DAI driver for extraction and creates a
new sound card with one DUMMY DAI link with a dummy codec
that will be used for extracting audio data from specific
points in the audio pipeline.

The probes debugfs ops are based on the initial
implementation by Cezary Rojewski and have been moved
out of the SOF core into the client driver making it
easier to maintain. This change will make it easier
for the probes functionality to be added for all platforms
without having the need to modify the existing(15+) machine
drivers.
